Xabagta polyvinyl chloride (PVC)

Sharaxaad Gaaban:

Polyvinyl chloride (PVC) waa polymer polymerized by vinyl chloride monomer (VCM) ee peroxide, azo compound iyo hindiseyaal kale ama iyadoo loo eegayo habka polymerization ee xorta ah ee hoos yimaada ficilka iftiinka iyo kuleylka.Vinyl chloride homopolymer iyo vinyl chloride copolymer waxaa si wada jir ah loogu tilmaamaa xabagta vinyl chloride.
PVC waxay mar ahaan jirtay balaastii ugu weynayd adduunka, taas oo si weyn loo isticmaali jiray.Waxaa si weyn loogu isticmaalaa qalabka dhismaha, alaabta warshadaha, waxyaabaha maalinlaha ah, maqaarka sagxadda, foornada sagxadda, maqaar macmal ah, tuubooyinka, fiilooyinka iyo fiilooyinka, filimka baakadaha, dhalooyinka, alaabta xumbo, alaabta wax lagu xiro, fiilooyinka iyo wixii la mid ah.
